220-1102 Operating Systems Practice Question
A technician is supporting a service-desk jump box. The immediate goal is to correct Linux file permissions. Which tool, control, or procedure is the best fit?
⚠ Common exam trap
Candidates often confuse Windows administrative tools (Event Viewer, System Restore, Local Users and Groups) with Linux equivalents, assuming they are cross-platform or that file permissions can be managed via user account tools rather than filesystem commands.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
chmod
The chmod command is the standard Linux utility for modifying file permissions, allowing the technician to set read, write, and execute permissions for the owner, group, and others. This directly addresses the goal of correcting file permissions on a Linux jump box, as it operates at the filesystem level using numeric (e.g., 755) or symbolic (e.g., u+x) modes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
chmod
Why this is correct
chmod changes the read, write and execute permission bits on Linux files and directories, letting the technician set the required mode for owner, group and others. It directly addresses the stated goal of correcting file permissions.
- ✗
Event Viewer
Why it's wrong here
Event Viewer is a Windows log console and cannot read or modify Linux permission bits; chmod or chown on the jump box is required. It tempts because Event Viewer is the standard Windows tool for reviewing system and security events, which would be correct when diagnosing Windows errors rather than Linux file permissions.
- ✗
System Restore
Why it's wrong here
System Restore reverts Windows system files and registry to a previous restore point, and does not exist on Linux or alter permission bits; chmod or chown is needed. It tempts because System Restore repairs Windows configuration damage, which would suit recovering a Windows host after a faulty change.
- ✗
Local Users and Groups
Why it's wrong here
Local Users and Groups is a Windows management console for accounts and group membership, not Linux file permission bits; chmod or chown is required. It tempts because it administers access rights on Windows hosts, which would be correct when adjusting account or group access rather than file permissions.
